Michelangelo Di Battista/RCA RecordsWant to learn all there is to know about Britney Spears? There’s a class in Brooklyn, New York, that will teach you, DNAinfo.com reports.

Two friends, Rachel Goldberg and Suri Ratnatunga, started Britney Spears 101, a workshop specifically dedicated to the life and times of the pop star.

The class, held in Rachel's apartment, features a multimedia presentation with GIFs, video clips and more. For $25, students get an overview of Britney’s personal life and career trajectory, including the ups and shaved-head downs. The class also presents an analysis of Britney's place in pop culture and how she’s contributed to the feminist movement. Drinks and Britney-themed snacks, such as "Baby One More Thyme" crackers, are also included in the price.

Rachel and Suri have already hosted a bunch of sessions, which have been attended by a mixture of hardcore Britney fans and people with a more casual interest in the singer. More classes will be added soon, and a maximum of 10 can attend each class.

ABC/Fred LeeTaylor Swift is continuing to make her fans’ dreams come true. After one of her biggest fans launched a Tumblr campaign to try to meet the singer, Taylor granted her wish.

According to E! News, Colleen Sullivan and her pal Tiffany Huang got their own private chat session with Taylor at a recent awards show in Los Angeles. On Sunday morning, Colleen, who had already planned to attend the show with Tiffany, found out that Taylor had followed her on Tumblr. Later that night, at the event, the two girls were taken to meet their idol.

Taylor talked to the girls at her dinner table and posed for photos with them.

Taylor, of course, is known for surprising her fans with personal attention. In the past, she’s sent them Christmas presents, hosted private listening sessions with them for her album 1989, and even offered one heartbroken fan breakup advice.

Jeff Daly/NBCWell, that was quick: Zayn Malik's first solo song is already out. Sort of.

Before Zayn left One Direction, producer and songwriter Naughty Boy told a British paper he'd been working with the singer on some solo material. Monday, Naughty Boy tweeted a link to a Soundcloud file containing a gentle acoustic track -- obviously in demo form -- titled "I Won't Mind," writing, "let the music do the talking guys. thank us later. :)." The file has since been removed from Soundcloud, though it's available to hear elsewhere.

According to People magazine, the Soundcloud file featured the caption, ""There is nothing but love for what was left behind. That's why we don't mind. ;) #zaughty #zinabad".

One Direction's rep confirms to ABC Radio that it is, in fact, Zayn on the track.

Before he posted the song, Naughty Boy had gotten into a Twitter battle with 1D's Louis Tomlinson, who accused the producer of "winding fans up" by retweeting a video that claimed "Naughty Boy saved Zaughty" and "Zaughty will rise." Louis responded by calling the producer "inconsiderate" and telling him to "grow up."

Naughty Boy thought Louis was referring to a tweet that he'd posted in 2012 insulting someone named "Louis" -- in this case, The X Factor judge Louis Walsh -- and told Louis to calm down. Louis responded, "I was talking about the video you tweeted. Clearly trying to wind the fans up ! Well you succeeded anyway."

Naughty Boy responded, "when ur gettin hate for some thing u didn't do, a bit of love can go a long way, that's why I retweeted, time will tell the real story guys."

Good Germs

Did you know that you and I are not com­pletely human? That’s right. If you go strictly by cell count, then you find that the human body is 90% bac­te­ria. There are some­where on the order of 100 tril­lion bac­te­ria liv­ing on or inside your body, and most of them live in your gut.

Now it’s true that many microbes carry dis­eases and can wreak havoc with your health. But most of the bac­te­ria that call your body home are benign, and many of them actu­ally serve a ben­e­fi­cial pur­pose. Here are just a few rea­sons why a peace­ful sym­bi­otic rela­tion­ship with these lit­tle life­forms is recommended.

Imbal­ances in gut bac­te­ria have been linked to dis­eases rang­ing from dia­betes and obe­sity to autism. In fact, it’s thought that gut bac­te­ria in obese peo­ple are more effi­cient at pulling calo­ries out of food, lead­ing to fat build up.

Germs can help calm you down. Some bugs are thought to affect the pro­duc­tion of chem­i­cals that have a calm­ing effect on the brain.

Bac­te­ria that live on the skin help to keep your outer layer in tip-top shape. Wash­ing your hands to often or overuse of hand clean­ing deter­gent can get rid of these bugs and lead to con­di­tions like acne.

Bac­te­ria may influ­ence the chance of hav­ing a heart attack or stroke. Peo­ple with ath­er­o­scle­ro­sis (a thick­en­ing of arte­r­ial walls caused by cho­les­terol) have dif­fer­ent bac­te­ria in their guts than healthy peo­ple. It’s thought the bac­te­ria in healthy peo­ple help pro­duce carotenoids, an antiox­i­dant that helps shield peo­ple from angina and stroke.

Some bac­te­ria help with the absorp­tion of med­i­cines. This makes it eas­ier for some peo­ple to take sub­stances like Tylenol, for example.

Some researchers believe some bac­te­ria in your body may com­bat can­cer. They see a rela­tion­ship between inflam­ma­tion of the gut, a decrease in ben­e­fi­cial bac­te­ria, and increase of E. coli, and occur­rences of bowel cancer.
